The US Space Agency (NASA) has delayed the launch of the Parker Solar Probe spacecraft for Saturday due to a technical problem and announced that it would try the launch on Sunday again.
The probe would have been launched at 9:45 am with a Delta IV Heavy Rocket at Cape Canaveral in Florida, but was thrown off 1 minute 55 seconds before the planned start because of a pressure drop in a helium tank.
The new option will be launched on Sunday at about the same time, but NASA emphasized that it was only when the technical problem was quickly resolved.
The Parker Solar Probe will look at the sun’s atmosphere. The space probe is closer to the star than before, into its outer atmosphere, ie its crown.
